Application lilcd December 26, 1855. Serial No. 186,801 (No model.)

To aZZ whom it may concern.-

Ilc it known that 1, JOHN \ViLsoN, a citizen of the United States, .residing at New York city, in the county and State of New York, have invented new and useful Improvements in Telegraphifire and Insulator l astenings, of which the following is a specification.

My invention consists of an improved contrivanee of the fastening device for securing telegraph-wires to the insulators more simply and eflicienlly than as now secured, as hereinafter described, reference being made to the accompanying drawings, in which Figure l is a side elevation of the insulator and a section of the telegraph-wire fastened together in accordance with my improved contrivanee, and Fig. 2 is a top view.

I make the insulator a. in any approved form and material, and with any desired means of connection with the supporting-arm, as the screw 1), to screw into a socket of the arm, or with the usual peg-socket, or both, and make a deep transverse notch or groove, 0, in the top of the insulator for the telegraplrwire d to lie in, the wire being stretched straight through the groove, and a suitable distance above the bottom of said groove 0, I make a circumferential groove, 0, in the exterior surface of the insulator, in which I wind the tie wiref one or more turns around the insulator and then tie the ends together, making an effective fastening without interfering with the telegraph-wire, which is entirely free of obstruetion and unaltered as to the lineal direction. The tie-wire may be fastened by its ends to the telegraplrwiro, instead of being tied together, as preferred. In this example I have represented the groove 0 as traversing the insulator at the middle of the upper end; but said groove may be located either side of the middle, as preferred.

It is apparent that the telegraplrwire lodged in the groove 0 and secured by the tie-wire is much more substantially fastened than when tied against the side of the insulator in the common way.

I claim as my invention- 1.. The improved insulator having the transverse groove 0 in the upper end for the telegraph-wire and the circumferential groove 6 traversing the groove 0 suitably for securing the tie-wire over the telegraph-wire lying in said groove, substantially as described.

2. The combination of the tie-wirc f with the insulator having the transverse groove 0 and the circumferential groove 0, and with the tclegraph-wire resting in the groove 0, sub stantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

JOHN \VILSON.
